R devel - Jan 2005 - XFIG color output (PR#7491)

Full_Name: Chris Haidinyak
Version: 2.0.1 & 1.9.0
OS: Linux x86_64
Submission from: (NULL) (139.95.251.9)


Hi,

   I am using R 1.9.0 (on Linux Redhat AS 3 - x86_64) and 2.0.1 (on Linux Fedora
Core 3 - x86_64) and am having problems using graphs created with the xfig
option.


1.9.0 problem - sometimes the graph output puts the color definitions in the
wrong place in the file. According to the xfig program, color definitions must
come before any object. For whatever reason, R sometimes produces xfig files
with color definitions in the wrong place. Run demo('graphics') to
recreate the
problem.


2.0.1 problem - This release seems worse that 1.9.0. All of the graphic output
from R to xfig (using the following script
   xfig()
   demo('graphics')
   dev.off()
produces only b/w graphs or no graph at all.

What is the problem? Am I doing something wrong? Please advise; thank you.

Best Regards,
  Chris Haidinyak

I can't.  What exactly are you doing, and in which file does this occur?
I have just tested all of them.

If perchance you were using onefile=TRUE, do read the comment in the help 
file.

Please produce a reproducible example.

Paul Murrell altered the alpha channel handling in 2.0.0, and missed this 
one.  I have a patch tested and about to go into 2.0.1-patched.
